HARROW.

. Application filed August 14, 1914. Serial No. 856,807. '3

T 0 all whom it may concern Be it known that]: CHARLES T. RAY, a citizen ofthe. UnitedStates. residing at Louisville. in the county of Jefferson and StateofKentuclcy,- have invented new and useful lmprovements in Harrows, fv'l1ich the following is a specification.

This invention has relation to farm implements such. as barrows, cultivators and the like; of the. type having a series of gangs of cutting elements relatively so arranged as to provide one pairofgangs disposed at opp0-- site sides ofthe line of draft and a second pair of gangs respectively arranged behind the gangs of the first pair. A two-way disk harrow best represents the type of implements to which the present invention has general reference and. for this reason, has been selected to exemplify the same. i

. The invention forming the subject of this application has more particular reference to the class of such implements wherein the real gangs of cutting elements are mounted on frames which are connected by vertical pivots to a frame which is laterally movable with respect to the front frame carrying the front gangs of cutting elements. and one of the objects; of tl'iepresent invention is to provide acorrelation of parts such that when. during the forward travel of the implement. the rear frame shifts laterally, to either the right or left. from its position centrallybehind the front frameor other predetermined position with relation to the front frame-the frames which carry the rear. gangs of cutting elements respectively will be automatically adjusted on their pivots relatively "to each other and to the said rear frame, thereby changing" their angular relation to the rear frame and the angular relationship of the rear gangs of cutting elements to each other and to the line of draft. the parts being further so ar ranged that this change in the angular relationship of the cutting elements to the line of draft will be such as to cause the rear frame with the gang frames and cutting 018-. ments carried thereby to be automatically restored to their proper positions with respect to the front frame and gangs.

Another. and amore important, object of this invention-is: to provide a correlation of parts such that lateral shifting of the rear frame, from its predetermined position will not only cause automatic adjustment of the rear gang frames pivotally with reference Patented June 6, 1916.'

to said rear frame but further will cause the rear frame to assume a ditferent'angularrelationship to the front frame and line of draft, the change in the-angular relationship of the rear frame to the line of draft and the change of the angular'relationship ofthe-y.

rear gang frames to the rear frame being such that they cooperate with each other in the restoration of the rear cutting elements -to their proper positions with respect to the front cutting elements in thesible space of time. r

These purposes, and others which will hereafter appear, are fully accomplished by the construction illustrated in the acc0mshortest pospanying drawings Which'exemplify the pre- I ferred embodiment of the invention. It should be understood, however, that the invention is not restricted to the herein illustrated embodiment and that itmay be otherwise and variously embodied withoutdeparting from its spirit or; the scope of the subjoined claimsfl I In the drawings, wherein like characters of reference denote 'corre'spondingparts in the several views; Figure 1.is a side eleva-. w

tion of a two-way diskharrow embodying the present improvements; Fig. 2 is a plan view of the same; Fig. 3 is a detail rear elevation showing one of the rear gang frames,

a gang of disks connected to said. gang frame and a part of the rear frame to which said gangframe is pivotally connected; Fig. 4 is a section on the line 4-4 of Fig.2; and Figs. 5 and dare views showing diagrammatically the positions of the parts when the rear frame is shifted laterally; Fig. 5 showing the positionof the arts when'the frame is shifted to the rig .and Fig; 6 showing the position of the parts when the frame is shifted to the-left o'f the normal central position indicatedhy the broken line -marked X in said 'figure'sl'f The implement constituting "the present invention includes afront frame YA and arear frame B. These frames are connected with each other by a pair of links C and D each of which extends from the front frame to the rear frame, the forward ends. of the links being pivoted to the frontframe A, and the rear ends of the link.- being pivoted to the rear frame B. The pivotal connections of-the links with the front frame A are i ofa character suclrth'at'the may swing 1 nected to the forward ends of the links C,-

and. D and loosely receive the hooks and 11, respectively. These linksform a medium of connection between the rear frame B and the front frame A which permits the rear frame to swing laterally as well as vertically.

Pivotally connected to the front frame A are a pair of frames E and F which re spectively carry a gang of suitable soil cutting elements, as the rotary disks 6 and f, for example. relatively so arranged that one gang of disks will throw the soil in one direction while the other gang of disks will throw the soil in the other direction. The frames E and'F. hereinafter, called gang frames, may be of any suitable construction and they are arranged so that their cutting elements, respectively, will normally be on opposite sides of the longitudinal. center of the implement, indicated by the line X. They are so mounted that they may be manually adjusted on vertical axes in order correspondingly to adjustthe angle of the disks with reference to each other and to the line of draft, and suitable means are provided for facilitating their manual adjustment to various selected positions and for locking them in their adjusted positions.

In the herein exemplified form of the invention the gang frames E and F are of the weight-box type and are connected by vertical pivots 14 and 15 respectively to two members 16 and 17 which members project y rearward from the frame A and are suit-j ably secured to the latter at 18 and 19-jre-- spectivelfv. The means preferably employed for adjusting the disk gang frames comprise two levers 20 and 21 suitably mounted on the front frame A and connected by links 22'.

and 23, respectively, with the frames E and F. the said levers being provided with suit; able latches 25 which respectively coopen ate with toothed sectors 26 and 27 for bolding them and the frames E and. F in various selected positions of adjustment relatively to the line of draft.

The rear frame B similarly is provided near its opposite ends with two gang frames G and. H which are pivoted thereto on vertical axes, shown at- 28 and 2-9, and these gang frames are provided with suitable soil cutting elements, as the gangs of disks 9 and h, respectively arranged behind the gangs of disks 6 and ffand set to throw the soil in reverse directions with respect to each other and to the gangs behind WlllCl'l they are respectively disposed.

-ang leas The gang frames G and Hbeing carried by the frame B partake of the lateral shifting movements of the latter, the said lateral shifting movements occurring by reason of the non-rigid character of the connection between the rear frame B and the front frame A and being of advantage in turning corners, but, should. be corrected in straight-ahead work. .To the means for correcting this by restoring the rear frame to its predetermined position with relation to the front frame for straight-ahead Work, this invention, as already stated, is mainly directed. To this end, the gang frames G and H are provided with suitable meansas the connecting rods and 31, for exampleby which they are connected with an appropriate part of the'implement, the

correlation of the parts being such that when the rear frame B is shifted laterally, the connecting rods 30 and 31 will serve to' turn the rear disk frames G and H on their vertical axes 28 and 29 automaticallyone frame in a direction the reverse of the other. The angles of the cutting elements 5] and. h with reference to each other and to the rear frame and line of draft are thereby changed to position whereinthe pressure of the soil against them causes them to return to their former angles, thereby restoring the rear frame B to its predetermined position with reference to the front frame A.

In order that this restoration of the rear frame relatively to the front frame may be more quickly brought about the side links C and D are disposed so that the lateral movements of the rear frame will be at an contradistinguished from parallel-to the front frame. This is brought about preferably by setting the side links at slightly diverging angles from their front ends to their rear ends.

It is only necessary, however, in order to bring about the desired angular shifting of the rear frame relatively to the front frame, that the links to be set obliquely of the implement in non-parallel planes and other arrangements of said links than the one herein particularly illustrated are considered to be within the spirit of this part of the invention.

It will be noted that by the arrangement referred to, the change of the angles of the rear disk gangs with reference to the line of draft is brought about first by the change of the angles ofthe rear frame relatively to the line/ of draft and second by the change of the angle of the gangs of disks relatively to each other and to the rear frame; and it 126 will be further noted that the correlation 'of the parts is such that these changes are very quickly-brought about, thereby making the implement very sensit ve. In order to further increase this sensitrveness of the 1111- 7 rear frame. shifts to' hc plement, it is preferred to connect the forward ends of the connecting links 230 and 51 with the side. links (I and I) respectively, as herein shown- In the herein exemplified form of the invention the connecting links 310 and 1&1 moreover. form elements of means whereby the disk frames (i and ll may be separately and manually adjusted into different positions. according to the character of the soil, and locked-to the side links (3 and l) respectively: said connecting, rods bein, shown as having their forward ends pivoted to mannally-operable levers I12 and 2525 which are pivotally mounted upon the side links (3 and l) and are provided with latches 35.3 which are arranged to engage any one of a series of teeth formed on sectors 36 and 37 secured to the side links (1 and l respectively.

It will thus he noted that the restoration of the rear frame to its predetermined position with relation to the front frame for straig'ht-aheml work is accomplisbwl in the most nracticable way by the emhmlimcut of the invention herein particularlyillustrated. for the reason that if the rear frame. moves laterallyto the right for example, (see Fig. 5) the rear endof the right hand link i), being farther from the center of the rear frame It than the front end of the link is from the center of'the front frame A. the link D will shorten the dis-- tance between the two frames at. this side of the imrdement, and at the same. time the link {7 at the left-halal side will len thenthe distance between the front and rear frames at its side of the implement. wherein the rear frame it is thrown at an angle creating a tendency to bring it back to the enter. in addition to this. the inside end. of the rightdiand disk frame ll is forced back by the connecting rod :31 while the inside end of the other disk frame. (i, is brought forward by the connecting link 30, whereby the a gles of the disk frames relatively to the rear frame ii are separately moved in directions to brine the rear harrow frame toward the center. The "car frame is thus very quickly brought back to its predetermined position. notwithstanding its entire lack of rigidity. ()bviously, if the left: (see Fig. (3'), a similar operation occurs -the link C shortening the distance between the two frames at the left-hand side and the link I) length eninp' the distance letween the two frames at the right hand side. while the. inside end of tluright-hand disk frame is brought forwardand the inside end of the left-hand disk is thrust rearward by the links 30 and :31 respectively.

The term frame when used herein with reference to' ea h of the parts A; B. "(2 and H is intended to be construed lower end of the sleeve 63.

plurality of elements conne ted to each" othcr---suitable for the purpose. I prefer, however. the particular constructions of these parts h rein illustratedand which will now beset forth in detail.

' The front frame preferably comprises two members fi s and :5!) which extend longitudinally of the implement and whose rear ends lll'(;li.t;ltllt*(l to upperand lower members H) and -ll. at about the center of the latter. the said upper'and lower members extendimr transversely of the. implement. Diagonal braces 42 and -t3- -.onnect the outer ends of the members l0 and -11 with the members. 258 and 5!) respectively, near the.

suitable construction is'preferably connected attached at ll and 15 to lugs 51 and 52 ex-v tendine from the outer bearings 45 and 48 respectively. while the rods'22 and 21-) have, their rear ends attached to similar lugs 53 and 5-lextending from the inner bearings it; and if. respectively. The levers 20 and ill are prvotallv connected to the members 3% and 35 of the frame A. and. as already stated. they are operable to adjust the frames I and i to various angular relatigms with respect to each other. the said frames E and I while being adjusted turning upon the pivots l4 and 15, which connect the rear ends of the members it; and 17 with the lugs 51 and 52.1-cspectivelv. 'lhc sectors 26 and 27 also art? attached to themembers 38 and 31) of the frame-A.

The rear frame it is preferably composed of spaced members 53 and :74 suitably connected together. andestends continuously :wross the implement. The disk carrying .framcst'l and if. are'of identical construot'ion and a description of one will answer for both. As shown most, clearly in Fin. 3, the frame comprises a crossbar 55 to which and 58 are, provided at their lower ends ,with sleeves 59 and 60. A. standard, '61.

which is arranged between the depending ends 57 and 58 of the yoke has its upper theelamp which alsirsecures the yoke 56 to said bar. This clamp-is marked 62. The standard 61- carries ais clamped a yoke. 56 whose depending ends.

The sleeves 59, and 63 form .135 end bent and secm'eclitothe cross bar by.

bearin s for the shaft of which supports a the gang of d1sks g or k and are arranged to space said. disks from each other. The clamp (52 is adjustable longitudinally of the cross bar and means, as the bolts 65, are provided for securing it in its adjusted position. This permits the distance between the gangs of disks g and h to be varied. The clamp (32 has a vertical extension which forms the pivot (28 or 29) hereinbefrn'e referred to as being the axis of turning movement of the rear gang frame ((l or ll) relatively to the frame B and this pivot extends through a sleeve (36 which has :1 lateral member 67 provided with a toothed sector (58. The gang frame (G or H) is also pivoted at 9 whereby it may be turned on a horizontal axis so as to adjust the gang of disks relatively to the frame B into different selected position inclined to the soil. and is held in its selected position by a lag 70 which engages the sector (38.

The rear ends of the side links C andD preferably are pivoted at 71 and 72 respectively (see Fig. 2) to lugs 73 and "74 which project forward from the castings 75 and T6. the said castings being preferably mounted so that they can be adjusted longitudinally of the members and 54: and being fixed in adjusted position by the clamp nuts 77 and 78. The connecting rods 30 and 31 have their rear ends pivoted at 79 and 80 respectively to the inner ends of the trans verse bars of the disk gangs G and H and their. forward ends, as already stated, in the herein exemplified form of the invention, are pivoted to the lower ends of the adjusting levers 32 and 33.
